Hi, We've faced the same issue with Debian Stretch. i40e driver with version 1.6.16 silently dropped ARP packets while not `promisc on` enabled on target interface. Update to linux-image-4.19 from backports (i40e driver comes with version 2.3.2) repository fixed this issue. Thanks for comments and suggested workaround. --- WBR, Mikhail
